What Is Skin Cancer?

Skin cancer is the most common form of cancer in the United States. It occurs when there are mutations in the DNA of your skin cells, and it begins in your skin's top layer, the epidermis. The epidermis has three types of cells:

• Squamous - the cells that lie just below the outer surface and function as the skin's inner lining
• Basal - cells that produce new skin cells and live beneath the squamous cells
• Melanocytes - the cells that make melanin, which gives skin its color. Melanin also protects the deeper layers of the skin from the sun's harmful UV rays.

Types of Skin Cancer

Squamous cell carcinoma

Squamous cell carcinoma is a very common type of skin cancer. It occurs on areas of your body exposed to the sun, such as your face, ears, and hands. It may appear as a firm, red nodule or a flat lesion with a scaly, crusted surface. People with darker skin are more likely to develop squamous cell carcinoma on areas that aren’t often exposed to sun as often, such as the legs and feet.

Basal cell carcinoma

Basal cell carcinoma is also very common and usually occurs on areas of your body exposed to the sun, such as your neck or face. It may appear as a pearly or waxy bump or a flat, flesh-colored or brown scar-like lesion.

Melanoma

Melanoma is a less common form of skin cancer, but is the most dangerous. It's one of the most common cancers in young adults ages 25 to 29. Melanocytes can grow abnormally and become cancerous when overexposed to the sun or any ultraviolet (UV) light, such as tanning beds. In men, melanoma most often shows up on the upper body, between the shoulders and hips and on the head and neck. In women, it's more likely to develop on the lower legs.

People with darker skin have a higher concentration of melanin, a skin pigment that acts a bit like sunscreen, but this does not make them any less susceptible to the sun’s radiation. Melanoma often appears under their fingernails or toenails, on the palms of their hands, and on the soles of their feet.

Melanoma is a serious and sometimes life-threatening cancer. If it is not caught early, it can grow deeper within the skin and metastasize, or spread, to other parts of the body, making it difficult to treat.

Risk Factors for Skin Cancer

• Fair-skinned, light hair/eyes
• Excessive sun exposure
• History of sunburns
• Family or personal history of skin cancer

• Sunny or high-altitude climates
• Exposure to certain substances such as arsenic

Reducing Your Risk

• Limit or avoid exposure to UV radiation
• Wear sunscreen year- round
• Wear protective clothing
• Avoid tanning beds
• Be aware of sun-sensitizing medications

Know Your ABCs

It’s important to inspect all moles and pigmented spots on your body. The American Academy of Dermatology recommends “Check your birthday suit on your birthday!”©

Check your skin for suspicious changes and make an appointment with your doctor or dermatologist if you notice anything out of the ordinary. Not all skin changes are caused by skin cancer, but if it is cancer, early detection offers a better chance at successfully treating the disease.

Sunburn Relief … in Your Kitchen?

After a little too much fun in the sun, try these home remedies to take the sting out of your sizzled skin:

Potatoes: Cut a raw potato in slices and rub a piece on your most painful spots. The starchy compound will help alleviate the sting.

Fat-free milk: Apply cool, not cold, milk to your skin using a clean cloth or gauze every 15 to 20 minutes. Repeat every two to four hours. The milk creates a protein film on your skin that eases your discomfort.

Strawberries: Mash a few up and slather on your sunburn; rinse off after a few minutes. The tannin content helps reduce the sting.

Oatmeal: Suffering from a full-body sizzle? Grind up a cup of the cereal in your food processor, add it to cool bathwater and settle in for a soak.
